A day at the lake - testing radio controlled speed-boats
Driving a Hydro-Sprint and a Mini-Sprint at a small lake in Graz, Austria.
Both boats are brushless-powered and have carbon-fibre rudders. The hydro-sprint is driven without a turnfin... - it just causes the boat to become unstably at higher speeds.
The Mini-Sprint's hull is optimized to run wet only at about 4 inches.
All without a crash or damaging one of the boats! ;-)
